wp_new_user_notification pluggable function

Hi All,

I’m trying to overwrite wp_new_user_notification as I don’t want to receive an email every time someone new registers.

I have copied the code from wp-includes/pluggable.php and put it into my functions.php file as:

if ( !function_exists('wp_new_user_notification') ) :
function wp_new_user_notification($user_id, $plaintext_pass = '') {
    $user = get_userdata( $user_id );

    $user_login = stripslashes($user->user_login);
    $user_email = stripslashes($user->user_email);

    // The blogname option is escaped with esc_html on the way into the database in sanitize_option
    // we want to reverse this for the plain text arena of emails.
    $blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);

    if ( empty($plaintext_pass) )
        return;

    $message  = sprintf(__('Username: %s'), $user_login) . "\r\n";
    $message .= sprintf(__('Password: %s'), $plaintext_pass) . "\r\n";
    $message .= wp_login_url() . "\r\n";

    wp_mail($user_email, sprintf(__('[%s] Your username and password'), $blogname), $message);

}
endif;

You will notice I have removed the first part of the function that should email the admin.

However it’s ignoring this function and still using the default one.

Any ideas why?

Thanks,
Sam
